.To alljwhom it may concern:

'of which 'the following is a speciiication. .My invention relates topaper gaging, guiding, and .feeding mechanisms `for type- Wntmgmachines.

The object of said invention'is to provide vsimple and efficient meanswhereby the' paper vmay be readily inserted inthe paperfeed mechanismwith assurance that the leading edge of the paper will always-be startedfrom the same point and thatthe lpaper will be properly positioned or suared therein and without the necessity of epe-nding upon the' eye orjudgment of the operator to determine whether the paper is properlyposiwherein like Areference characters representVl tioned or Whether itis straight or not;

v To these and other ends, which will. hereinafter appear, my inventionconsists in the novel arrangement and combination'of parts -to behereinafter described and claimed.

Referring to the accompanying drawings,

. corresponding parts in the several views,

A Thevpaper-feed mechanism is shown in the present instance' as comprisingtwo springpressed'frames4 and 5, Figs. 4 and 5, which are pivoted totheend plates, as indicated at 6 and 7, respectively, Figs. 2 and The frame4 carries a' paper-blade 8, which is pro- 1 yvided on its outer facewith -a scale 9, and carried-'by the blade atthe under face thereof is aloosely-mounted paper-feedroller 10, whiehis normally maintainedincontact with the platen, as indicated in the end plates of the framev 4has an arm that extends to the rear of the pivot 6 of said Figl 3. Eachof frame and is notched, as indicated at. 11, for

4cooperation with a pin 12, that is carried by an end plate of the frame5 and extends inwardly therefrom, vthe pins and notches cooperating tollock the frames 4 and 5 in the positions indicated in Fig. 2, as willhereinafter more clearly appear. Outside of each end plate of. the frame5 is a link 13, one end of which is pivoted at 7 to the platen-frame,

the other end of the link being pivoted ati17 to the frame 5,- the link13 thus pivotally connecting the `frame 5 to' the platen-frame.

-The roller and,paper-blade-carrying frame 4 is provided with a nose,cam, or bearing-surface 14, which isadapted to bear against a paer-blade 15, carried'by the frame 5. It wil be understood that when theframe 4 is moved'from the position indicated in Fig. 3 of theIdrawings'to that shown'in Figs. 2 and 6 the. projection or nose 14will'cause the frame 5 to be moved with it until the arms on the frame4, which have the notches 11 therein,v are b'rou',1 1;ht into contactwith the lpins 12, andsaid'pins spring into notches 11 and arrestfurther lbackward movement of the frames 4 and 5 `and lock them in thepositions shown in Figs. 4 2. and 6.' Springs llare adapted to bearagainst pivot-pins 17 for the links 13 lwhich pinsin the-presentinstancel are formed by the ends of theshaft or rod of the paper-feedrollers 18. From an inspec-f.

IOC

tion of Fig. 1 it will be seen that one of these .springs 16 is carriedat each end of the platenframe and coperates with its pin 17. While thetendency' of the springs m16 is normally to maintain the frames in thepositions indicated in Fig. 3, with the paper-feed rollers in contactwith the platen, the frames when 1 regulated by a set-screw 19, and asecond projection 21 on each of the side or end spring 2O may beemployed to bear upon the plates constituting portions of the frame 4.These springs 2() tend, further, to maintain the parts )in each of thepositions indicated in Figs. -2

'and 3 by reason of their coperation withA the flattened portions 22 oneach nose 21 when 'the parts are moved to the positions shown.Preferably I provide finger-pieces 23 on the fra'me y4 lin order tofacilitate the movement y of the frames 4 'and 5 by hand from theposition shownin Fig. 3 to that indicated in Fig. 2, `or vice versa.

The fraine 5 in addition to the feed-rollers 18 is provided with what Iterm a paper stop or gage 24, which preferably is in the nature of aflat lplate or bar that extends throughout or substantially throughoutthe length ofy the platen, though it may be notched 'or recessed atvarious points of its 'length to provide a set of stopsor gages, whichproject from the bar. parts are inthe positions indicated in Fig. 3 ofthe drawing, this paper-stop will be maintained in a position where-itaffords no obstruction to the free passage of the paper around 'the'platen. When, however, Athe fpa'rts are moved to 'thepositions/indicated in Fig. 2, the angle whichthe plane of this stopbears. to thel surface of the platen is changed and the lower edge ofthe stop is brought. closer to the platen andthe `stop is interposed 'inthe path of the leading end or edge'of the paper andcons'ti'tutes-anabutment stop'or gage by means of which 'the y paper can be straightenedand properly and evenly fed on the platen, at the same time assuringthat thev successive sheets Aintroduced into the machine will always Ibestarted fromy a given point, or, Iin other words, that the leading edgesof successive sheets introduced into the machine will always be at agiven distance from the printing-line and will be squared withrelationthereto. ,This is clearly indicated in Fig. 2

of the drawing, wherein lthe paper 25 has its leading edge or end 26resting' upon the paper-stop. By having the paper-stop extend throughoutthe length of the platen paper of various Widths can be efficientlytrued or straightened on the stop. After the paper has been inserted inthe manner described,

` and a's indicated in Fig. 2, the frame 4 is depressed, therebyrelea'sing the notched portions 11 from the pins 12, and the parts willassume the positions shown in Fig. 3 of the drawing. It will be observedthat when the parts are in these last-mentioned positions thepaperis'rmly clamped upon the platen and the feed-rollers are incooperative relation to the platen to feed the paper forward therewith.It will likewise be seen that the paper-'sto 24 has been moved beyond`the effective 'aces of the paper-feed mechanism,

' or those faces thereof which contact with the paper, and has beenmoved to a position where it no longer affords an yobstruction to thefree movement of the paper. In' other words, when the parts are in thelpositions shown in Fig. 2the paper-stop 24 is adjacent to the platen,while the feed-rollers and blades are maintained away from the platen,whereas when the parts are in the positionsr shown in Fig-3 thefeed-rollers and blades `are in contact with platen and the stop 24 ismoved away from 'the platen.; The paperblades 8 and A15 'co 'crate withthe paper u on opposite sides o the printing-'lindas is c earlyindicated in Figs. land 3, so as'l to write on short sheets of paper orcards and so as tornaintain the paper pressed 'against the platen at the`printing-line.

From theforegoing description it will be observed that the feed-rollersare located in advance of the paper stop or gage 24 and that whenever.theV rollers are" moved #a position where ythe paper is adapted tdoibereadily inserted the paper-stop 24-is always effective to'receive orcoact with the -leading end or 'edge ofthe paper and to act .as 'anabutment to square it, yand the, vpaper may then be clamped in position4on the platen .without disturbing 'the' arrangement yof the lpaperattained 'with 'the aid of said stop.

Furthermore, a single movement ofthe alll arts of the. `paperfeeding`mechanism from coperation or contact with the platen, and 'thisfsamemovement brings'about `the interposit ion of the paper-stop '24, so'that lit ywill constitute an abutment for the'proper positioning of thepaper.

lIO

Aframe 4 is all that is required to withdraw orpaper-feeding device 18,considered withl v relation to the direction of line-feed of the paper,Vand when the roller is 'forced away:

from the platen the paper may be introduced between the face of theroller and the platen and properly positioned against the paperstop 24.Then when the feeding device 18 is moved into coperative feedingrelation to the-platen, as shown in Figf3, the effective face of theroller will clamp-the paper tothe V platen wit-hout disturbingthe'arrangement Isp `by Letters Patent, is-

of the paper.

' In f"ldi.'onto the mechanism thusfar described I may provide apaper-shelf` 27, which receives the paper from the platen.

It is obvious, however, that any suitable mechanism may be employed forthis purose.

while I have; Shown mi vdescribed .with

considerable detail one form of mechanismembodying my invention, itshouldbe un-v derstood that varibus changes in the structure may be madewithout departing from the spi.it of my invention and in order to adapttl.;y invention to various forms of type-Writing machines.
